I am trying to get a directory argument from cli using node js. Suppose my command line is: node myapp.js D:\test\strange. when I do console.log(process.argv[2]) it shows: D:teststrange how do I get D:\test\strange

CodePudding user response：

The problem is in the command line processor of the shell used to run node. Using

console.log(process.argv)

as the contents of log-argv.js,

1. Under the Windows command line processor CMD.exe

    node log-argv D:\test\strange
   

   outputs (in test directory D:\localhost\SO)

    [
      'C:\\Program Files\\nodejs\\node.exe',
      'D:\\localhost\\SO\\log-argv',
      'D:\\test\\strange'
    ]
   

   which is what was wanted.

2. Under git-bash.exe for windows however, the same command line outputs

    [
      'C:\\Program Files\\nodejs\\node.exe',
      'D:\\localhost\\SO\\log-argv',
      '\x96D:teststrange'
    ]
   

   suggesting node is relying on the command line processor, used to run it, to parse the command line string for it. This is entirely consistent with C programming practice.
